Hi, I was wondering if anyone can help. I currently have a setup at work in our accommodation blocks to allows users to access internet via wireless. I have users connecting to wifi routers, which currently ends up going through a transparent squid proxy. User's currently pay me for access to service where I will add there MAC access to access points, but this is alot of work. Is there a way I can control access to internet using my ubuntu squid proxy? E.g. user issued a password/key and once entred user has net access, so no key no internet. Any help would be could, and as a newbie to linux the clear it is, the better.

how to connect ssh in ubuntu system. can any one help me

When I first installed Server version of Ubuntu 7.10 I followed the suggested method and did not set a root password. I created one user and I assumed that user automatically would have the ability to install applications and run administrative tasks. I just logged in as that only user and could not run Gedit command. It tells me to tell my administrator to install it. I tried some commands I found on this site and nothing seem to work. I decided to assign root password so I typed sudo passwd and it asked me to enter my current pw I did. Then I was prompted for a new password I entered a new password. I thought that would mean now I could login as user "root" and enter the new password. It did not work. I put my name and used the new password and I was able to login. Am I doing something wrong? Your help is appreciated. Also, I tried to install the GUI versions to make life easier but don’t seem to work. 

I'm running Feisty 7.04 Server(no GUI) on a G4 Powerbook (15" Titanium) as the sole OS.   I'm administering it with SSH from a WindowsXP machine so I don't need/want the screen live on the Tit.   Admittedly, the screen does go blank after a while, but it's still illuminated.   How can I power it down completely from the command line?  I've seen reference to 'xset' and 'DPMS',  but I think they are only for X11, aren't they?  I hope this is less painful than my Yellow Pig experience.

Hi there,

I successfully installed the Ubuntu server edition on a PC of mine on partition hda1.

Here's how I partitioned the harddisk:
hda1 has 5gb
hda2 has 5gb (currently emtpy)
hda3 has 1gb and is /tmp

The rest is /usr

How can I backup my existing Ubuntu installation into partition hda2? I want to be able to boot from hda2 if the installation in hda1 gets corrupted.

Can I use the same /tmp partition for both installations?

My server is running great,
I have :
gnump3d - media server
Gallery - pic albums
apache2,
samba,
ftp,
SSH,
secure VNC,
& more

She has been running like a dream. Can view site @
